Despite the title, this isn’t about 9/11. The three books in this collection were written in the sixties. They don’t feel like sixties books, though—these could easily have been written today.

The only humans left on Earth are on a single island, in a single city. There’s another city on the mainland, but a strange radiation barrier appears, dousing that city in radiation and locking the people on the island off from the rest of the planet.

There’s an enemy that may or may not exist beyond the barrier. An escaped prisoner finds himself in the middle of the radiation, but perfectly healthy. He meets Neanderthals and mind-reading giants as he tries to get home. Things get much weirder.

There’s an enjoyable strangeness to these three books. They’re a great combination of advanced technology, unintended consequences, and good old political intrigue.

While some of the dialogue was unrealistic, the stories are interesting, well-crafted, and smart as hell.

Recommendation: Get it at the library. It’s a damn good read, but not necessary for a shelf.
